This week, I have been mostly working on...

I've been tinkering around with bits of technology since I was five years old. I used to take the telephone apart at home, just to see how it worked.

After a couple of years I could even put it back together again - and sometimes it would continue to work.

I originally posted the Laser Harp video to show some people in the UK. It's turned out to be quite popular, so I decided to post other project videos too...
